Hi I am owning a 5d mark2.I tried thru several services to find out how many shutter counts my camera has. But every Programm and site tells me the information is not available. I bought the camera 2nd hand and I am afraid I bought a stolen one. Is it possible to hide that information? And if so how can I deactivate it. Thanks a lot.

I think the OP meant to ask if there is a way to deactivate the way a thief might have concealed that the camera was stolen, i.e., bring its stolen status to light, not hide it.

It may be possible to make a camera hide its EXIF data; I am not very tech-knowledgeable, so would not know.

There are means to track a stolen camera by alerting when its EXIF data appears in on-line images. At least one website offers this service.

In the USA, the serial numbers of stolen items are entered into national and state databases, if the owner provides that information to police, so that if the police run a serial number check, the stolen status will become immediately apparent. In Texas, and probably most or all other states in the USA, the serial numbers of items that are pawned or sold at licensed pawn shops are entered into the police data bases.

If a stolen item crosses national boundaries, its ability to be traced by police diminishes, depending upon international arrangements to share the data.
